The objective of this study was to assess the degradation rates chrysene and benzo[a]pyrene, as well removal aluminium iron from contaminated soil collected in upper layer (0–30 cm) Lagos, Southwest Nigeria. Trametes versicolor isolated used experiments, with plantain peels support. After 8 weeks, 81.0% achieved by T. , adding support increased 91.0%. Benzo[a]pyrene less degradable, 38.0% 49.1%...

Mycelial pellets of Trametes versicolor, grown at initial glucose and ammonium tartrate concentrations of 10 g/l (56 mM) and 0.442 g/l (2.4 mM) respectively, decolorized successive additions of the same dye (Amaranth) and of different dyes and dye mixtures. Decoloration commenced by Day 3 and all dyes were decolorized at high rates during the next 12 days. Glucose was consumed at a steady rate ...

Cement bonded particleboards were manufactured from hornbeam (Carpinus betulus L.) wood particles. Hydration tests were carried out to determine the inhibitory index in order to characterise wood-cement compatibility. The results revealed that the mixture of hornbeam -cement can be classifi ed as moderate inhibition. Two wood: cement ratios were applied in this study, namely 1:3 and 1:4, for th...

This study presents new and alternative fungal strains for the production of ligninolytic enzymes which have great potential to use in industrial and biotechnological processes. Thirty autochthonous fungal strains were harvested from Bornova-Izmir in Turkiye. In the fresh fruitbody extracts laccase, manganese peroxidase and lignin peroxidase activities, which are the principal enzymes responsib...

A simple and highly efficient protocol using magnetic mesoporous silica nanoparticles (MMSNPs) with metal affinity ligands was developed to directly capture laccase from Trametes versicolor fermentation broth. The Cu(2+)-chelated magnetic mesoporous silica nanoparticles (MMSNPs-Cu(2+)) with pore sizes ranging from 3.6 to 27.1 nm exhibited size selectivity on laccase capture from the fermentatio...

Genes encoding thaumatin-like protein (TLPs) are frequently found in fungal genomes. However, information on TLP genes in Polyporus umbellatus is still limited. In this study, three TLP genes were cloned from P. umbellatus. The full-length coding sequence of PuTLP1, PuTLP2 and PuTLP3 were 768, 759 and 561 bp long, respectively, encoding for 256, 253 and 187 amino acids. Phylogenetic trees showe...

Previous preliminary studies showed good efficacy of treatments based on a mixture of siloxane materials, functionalized with amino groups and coupled with copper, against the brown rot fungus Coniophora puteana (Palanti et al. 2011). In the present work, a one-step impregnation was performed on two sets of samples differing in size, in order to verify and compare the homogeneity of treatments....

ÐA number of model compounds resembling the fundamental bonding patterns of residual kraft lignin, including a series of stilbenes, were incubated with laccase from Trametes versicolor in the presence and absence of deligni®cation `mediators' ABTS and HBT. The condensed kraft lignin model compounds seem to undergo initial degradation by laccase mainly via benzylic oxidation, demethylation and h...
